I got sick during development so I couldn't get a tutorial up and running, but here is a brief explanation of how to play:
Arrow Keys - Move Piece / Move Matchmaker Up Arrow Key - Hard Drop X - Enable Matchmaker / Activate Matchmaker Z - Cancel Matchmaker
Your objective is to clear the fruits and get your highest score using the Matchmaker, a 3x3 area that checks and clears fruits inside, but the catch is that you can only clear them if they match specific combinations of the same fruits, like 3-in-a-row, Diagonals, etc.
